Let’s talk about investments. When you’re putting your money into a business prospect, you’d never put all your life savings into one project, right? As the wise have said before us- never put all your eggs in one basket.

Trying to save your basement from an unwanted flood and considerable property damage with one electronic/traditional sump pump is a similar mistake. It’s like going to war half-geared.

If you don’t have any other machine as a failsafe when things go south, then you’d be left with regrets and losses during a calamity. So, getting yourself a battery-powered sump pump is going to further fortify your basement’s defenses.

Many people ignore getting a backup pump because they’re worried about the installation. Well, with the comprehensive guide we’ve prepared, you don’t need any expert help.

Things You Will Need to Begin

– A battery

– Battery acid pack

– Two check valves

– Y connector a 45 degrees elbow

– 1-1/2 inches PVC pipe

– PVC primer

– Pipe adaptor

– Cement

– Water bucket

How To Install A Battery Backup Sump Pump Step By Step

Note: Take out the remaining water for the sump pit before you begin and, if necessary, use an empty bucket. It is essential because you have to make a connection between the backup pump and the primary sump pump that will be inside the pit.

Step 1: (Piping and Installing Discharge Line)

  • Cut the discharge pipe about one foot above the floor
  • Install the check valve on the top of the pipe (Make sure you tighter the hose clamp)
  • The arrow on the check valve should be pointing up; otherwise, it will not prevent the backflow of water
  • Take another pipe and cut it about one inch above the floor of the sump pit
  • Stick a pipe adaptor on that point and screw it to the backup pump
  • Then make a 1/8 inches hole in the backup pipeline at 45 degrees angle (It should be angled toward the bottom of the sump to prevent water splash. If the hole is not angled correctly, it may cause an airlock in the backup pipe)
  • Now position the battery backup inside the pit and make sure it is parallel to the primary pump
  • Keep minimum distance so that the machines don’t touch each other
  • Attach a Y connector with the primary piping
  • Use a PVC pipe hose with the main pump
  • Then attach another PVC pipe and 45 degrees elbow with the backup pump
  • Once all the adjustments are perfect, stick them properly with glue

Step 2: (Connect the Backup System)

  • Position the float switch about 6 inches above the discharge pipe securely with a wire tie (Select a suitable level of water limit so the backup battery can activate)
  • Remove the security tag from the backup pump and plug it into the back of the control unit
  • Connect the battery wires to the terminals where the black one is in the negative post, and the red one is in the positive post (Tighten the wing nuts carefully)
  • Attach the battery fluid sensor cap by replacing it with the second cap from the positive post (It comes with a hole above the cap so purchase one if it’s not provided)
  • Insert the fluid sensor into the new cap
  • Plug the charger and the AC outlet on the wall
  • Secure everything and plug in the main AC pump

Your installation is complete, so you are good to go with your sump pump.

However, instead of buying a completely new unit, if you prefer buying a battery as a new power source for your sump pump, you must continue reading further.

How to Install a Battery Backup to an Existing Sump Pump

Things to Purchase

  • A battery
  • Protective case for the battery
  • Battery acid pack
  • An AC/DC interface
  • A red and a black cable

Step by Step Installation

  • Turn off the power sources and position the battery near your sump pit
  • Connect the battery cables with the interface (The power button must be OFF)
  • Link the pump with interface AC supply and then plug in the interface with an AC supply
  • Attach the red cable to the positive terminal of the battery and black wire to the negative terminal
  • Now, unplug the primary AC connection and check whether the sump pump works or not. So, if it works, that means you have successfully added battery backup to your existing sump pump.

How to Test Battery Backup Sump Pump

Testing the pump is pretty straightforward. It would be best if you took these measurements beforehand because a little negligence might cause floods all over the house. So, let us check this out.

  • Make sure that you have plugged in your backup pump and charged it well
  • Unplug the primary sump pump
  • If there is no water, fill the pit and let the backup pump discharge water (For better inspection check after 30 minutes)
  • Test the float switch by pulling it up and down. If the pump kicks out the water while you pull the switch up, then your battery backup pump is doing great

So, if your pump is unable to discharge water without the connection of the primary sump pump, you might assume there is a problem.

Warnings

  • You should confirm a good location for installing the battery backup because you have to set the backup pump alongside the primary one. So, you won’t be able to mount everything properly if there is not enough space
  • Make sure that you have kept all electrical connections OFF because it might cause an accident
  • Do not attach all the pipes without testing because it would be difficult to separate once you glued them
  • Keep all the tools in your inventory before starting the installation

Final Verdict

Battery operated sump pumps are quite efficient, especially when there is an electrical outage at your home. Batteries naturally store electricity, so it makes sure that the pump does not die during a power outage.

Furthermore, it is effortless to install, so following a few simple steps, you can do it yourself. Once you’ve got it ready, you won’t have to worry about any floods even when the municipal electricity fails you.
